Description
The AddOn Cisco® QSFP-100G-2DW28-S-AO is a 100GBase-DWDM PAM4 QSFP28 transceiver designed to deliver high-speed data transmission over single-mode fiber (SMF) with a reach of up to 80 km using an ITU-T C-Band DWDM channel DW28 at 1554.94 nm. Fully compliant with SFF-8665 and 100 GHz ITU grid standards, this transceiver is ideal for metro, access, and enterprise network deployments that demand long-reach, high-capacity connectivity.
Engineered for seamless integration, it is 100% compatible with Cisco® hardware and supports hot-swappable installation for minimal downtime. With built-in Digital Optical Monitoring (DOM), network operators can monitor critical parameters such as optical power, temperature, and voltage in real-time. It also features robust ESD protection, low EMI metal housing, and full RoHS and TAA compliance, ensuring reliability and adherence to international trade standards.
Each transceiver is uniquely serialized, application-tested, and backed by AddOn’s limited lifetime warranty, ensuring dependable performance and OEM-level compatibility in demanding optical network environments.
